ABSTRACT
The aim of this work is to study the behaviour of a cold rolled forming thin-walled steel column by the finite element method (FEM). The non-linearity of this problem is due to the plasticity, large displacements and contact phenomena. We study the plas-ticization stresses and roller forces for different plate thickness, and present the results and conclusions. Indeed, such non-linear applications are today of great importance and practical interest in most areas of engineering and physics.
